GitLab Reviews
3.5 (2)Works, with some caveats
Mixed feelings about GitLab after using it for a while. On the plus side, all-in-one devops platform reduces tool sprawl. That said, smaller open-source community than github, which held us back from rating it higher.
Does exactly what we need
GitLab has quickly become part of our daily workflow. Good built-in security scanning. One minor gripe: ui can be complex due to feature breadth, but it hasn't been a dealbreaker. Would recommend to anyone considering it.
